DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-4 A rotary riveting machine with a fixed structure includes a frame 1, a guide rail 11 symmetrically arranged on the frame 1, and a driving plate 12 slidably mounted on the guide rail 11. A lifting assembly 3 is arranged on the top of the frame 1, and a rotary riveting machine body 4 is fixedly mounted on the lifting assembly 3. A support frame 2 is fixedly mounted on the end of the driving plate 12 away from the guide rail 11. Four slots 21 distributed in a circular array are opened on the support frame 2. A support rod 22 is rotatably mounted in the slot 21. A vertical plate 23 is fixedly mounted on one end of the support rod 22. A clamping mechanism 24 is symmetrically arranged on the vertical plate 23. The support frame 2 in the entire frame 1 is coaxially arranged with the rotary riveting machine body 4, which can meet the needs of vertical rotary riveting, and the workpiece can be quickly fixed by the support rod 22 and the clamping mechanism 24, which is more convenient to use.

[0025] Reference Figure 2 The clamping mechanism 24 includes a clamping rod 241 fixedly mounted on the vertical plate 23 and a rubber head 242 fixedly mounted on one end of the clamping rod 241 away from the vertical plate 23. When the support rod 22 and the vertical plate 23 rotate, the clamping rod 241 and the rubber head 242 can be driven to move, thereby clamping the workpiece, ensuring that the workpiece is more stable during riveting.

[0026] Reference Figure 2 The rubber head 242 is semicircular and has a plurality of anti-skid bumps. When the rubber head 242 is clamped, the anti-skid bumps on the rubber head 242 can increase the contact area with the workpiece, making the clamping more secure.

[0027] Reference Figure 3 A turntable 5 is rotatably mounted in the support frame 2, and four transmission plates 51 are hingedly connected to the turntable 5 and arranged in a circular array. One end of the transmission plate 51 away from the turntable 5 is hingedly connected to one end of the support rod 22 away from the vertical plate 23. A driving mechanism 52 for driving the turntable 5 is arranged in the support frame 2. When the driving mechanism 52 drives the turntable 5, the support rod 22 can be driven to rotate in the slot 21 through the transmission plate 51, and the support rod 22 can rotate in two opposite directions, thereby increasing the clamping range of the support rod 22.

[0028] Reference Figure 4 The driving mechanism 52 includes a bracket 521 fixedly mounted in the support frame 2 and a servo motor 522 fixedly mounted on the bracket 521, and the output end of the servo motor 522 is fixedly connected to the turntable 5. When the servo motor 522 on the bracket 521 is turned on, the turntable 5 can be driven to rotate, thereby driving the turntable 5.

[0029] Reference Figure 4 The bracket 521 is U-shaped and is arranged at the diagonal position of the support frame 2, thereby ensuring that the servo motor 522 is more stable during operation.

[0030] Reference Figure 3 The initial position of the transmission plate 51 is inclined with respect to the slot 21. This ensures that the transmission plate 51 can drive the support rod 22 to rotate in the opposite direction when the rotating disk 5 reciprocates.

[0031] Reference Figure 2 The support rod 22 is arranged at the center of the slot 21 so that the support rod 22 can rotate in the opposite direction.

[0032] The specific working principle of the present invention is as follows:

[0033] First, the driving plate 12 can be pulled to slide along the guide rail 11. At this time, the support frame 2 on the driving plate 12 can be moved out of the position directly below the rotary riveting machine body 4. The staff can place the component in the center of the support frame 2, and then the servo motor 522 can be started. When the servo motor 522 is turned on, it can drive the turntable 5 to rotate. When the turntable 5 rotates, it can drive the support rod 22 to rotate in the slot 21 through the transmission plates 51 hinged at both ends, so that the workpiece is clamped by the clamping rod 241 and the rubber head 242 on the vertical plate 23, and the servo motor 522 can drive the support rod 22 to rotate in the opposite direction when it is reversed. The clamping mechanism 24 is symmetrically arranged on the vertical plate 23, ensuring that the support rod 22 can fix the workpiece by clamping or supporting it, so that the processing range of the workpiece is wider. After the workpiece is fixed, the driving plate 12 can be reset, and the lifting assembly 3 and the rotary riveting machine body 4 can be turned on to start riveting the workpiece.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
